The operating lever 25 is thendepressed causing the clamping members (Z, c, to force the arms of theclothes-pin against the reciprocating files and at the same time the lug33 is brought into engagement with the top of the clothes-pin. After thearms of the clothes-pins have been grooved to the desired extent, theoperating lever 25 is released whereupon the spring 27 will throw theclamping members out of clamping position and raise the lever 31 leavingthe clothes-pin free to be ejected from the holder by the spring pressedplunger 40. With the use of the present machine, the arms of theclothes-pin are grooved as at 1 referring to Fig. 4.

It is, of course, obvious that my invention is susceptible of variousmodifications and changes which are within the spirit of the inventionwithout departing from the scope of the following claims, it beingunderstood I that the present disclosure of myinvention is by way ofillustration only and it is not to be taken as restrictive of myconception.

I claim as my invention f 1. In a machine of the character described, aholder adapted to receive a clothes-pin or the like, a tool extendingthrough said holder, and means for moving the arms of the clothes-pintowards each other and against said tool during operation upon saidarms. 2. In a machine of the character described, a reciprocating tool,a pair of clamping arms constantly positioned, one to each side of saidtool adapted for simultaneouslyclamp ing the work and moving the sameinto engagement with the tool, and means for moving the clamping memberstoward the tool.

3. In a machine of the character described, a holder adapted to receivethe arms of a bifurcated article, a longitudinally reciprocating filepassing through said holder, and means constantly arranged at oppositesides of the file for moving the arms of the articles against said fileduring the filing operation. I

4. In a machine of the character described, a holder, a reciprocatingtool, a pair of clamping members constantly aimanged, one to each sideof said tool, means for moving said clamping members towards one anotherto force the parts of the work against said tool, and automaticallyoperating means for withdrawing said clamping members from operativeposition. I

5. In a machine of the character described, a reciprocating file, a pairof clamping. members constantly positioned,'one to each side of saidfile and adapted to force the arms of an article straddling said fileagainst said file, a connection between said levers, and an operatinghandle connected to said levers for forcing the same towards one anotherduring the filing operation.

6. In a machine of the character described, a reciprocating tool, aholder adapted toreceive an article with parts thereof straddling saidtool, a pair of clamping members constantly positioned, one to each sideof said tool and adapted to force'the articles thereagainst duringoperation upon said article, one of said levers being of the first classand the other ofthe second class, a connection between said levers, andan operating lever for actuating said levers.

7. In a machine of the character described, a holder having a socketadapted to'receive the arms of bifurcated articles, a tool pass ing atright angles through said socket, a clamping member carried by saidholder to each side of said socket and adapted to extend thereinto forforcing the arms ofthe articles against said tool', and operating meansfor said clamp-ing members.

8. Ina machine of the character described, a holder adapted to receivearticles to be operated upon, a reciprocating tool, a pair of clampingmembers constantly positioned one to each side of said tool, means forurging said clamping members towards one another to move the articlesagainst said tool during operation upon said articles, and means forholding said articles steady within said holder. c

9. In a machine of the character described, a holder having a socketadapted to receive the articles to be-operated upon, a reciproeatingtool extending across said. socket, a pair of clamping members carriedby said 105 holder and adaptedto force the straddling portions of thearticles against said tool, means for preventing the articles frommoving in the direction of movement of said tool, and connectionsbetween said clamping 110 members and last mentioned means whereby thesame are operatedin unison.

10. In a machine of the character described, a holder having a socketadapted to receive the arms of a bifurcated article, a 115 tool forgrooving the opposing faces of the arms, clamping means for forcingthearms into engagement with the tool, and means rendered operative byengagement with the article for ejecting the articles from said 12.0socket when the clamping means are released. I

11. In a machine of the character described, a holder having a socketadapted to receive the arms of bifurcated articles, a tool 1% extendingacross said holder, clamping members for forcing the arms of. thearticles towards each other and against said tool, and

a spring pressed plunger for ej ectingthe articles from said socket whenthe clamping we members are Withdrawn from clamping position.

12.1n a machine of the character described, a holder having a socketadapted to and straddling said file against said file dur{ ing thefiling operation,

let. In a machlne of'thecharacter de? scribed, a holder having a socketadapted to j receive the arms or" a bifurcated article, a reclprocatingfile for-grooving the opposing i y faces of thearms, clampingmeans formoving the arms into engagement With the file during the filingoperation, and means for ejecting the articles-from said socket throughthe same end through which they are insert-Z ed into the socket.
